From cdab76a0f45d03b28a97e11345b4f4b457a83264 Mon Sep 17 00:00:00 2001 From: Dietmar Eggemann Date: Fri, 3 Feb 2017 20:37:16 +0000 Subject: [PATCH] ANDROID: arm: wire frequency-invariant accounting support up to the task scheduler Commit dfbca41f3479 ("sched: Optimize freq invariant accounting") changed the wiring which now has to be done by associating arch_scale_freq_capacity with the actual implementation provided by the architecture. Define arch_scale_freq_capacity to use the arch_topology "driver" function topology_get_freq_scale() for the task scheduler's frequency-invariant accounting instead of the default arch_scale_freq_capacity() in kernel/sched/sched.h.
